How the bone scan equipment is?
Common x-rays are used.
What are dark spots seen on a bone after a bone scan?
I'm not 100 percent sure, but I believe that the "dark spots", often called hot spots, refer to abnormal amounts of radionuclide in the bone, determining that it is infected or diseased. Though the previous person isn't completely wrong, it really depends on how the images are displayed. If there is a white background, anything dark = increase tracer uptake, which could be a multitude of things, from trauma (bruises), to fractures, to cancer. Other scans are performed to distinguish between the many possibilities. Basically the premise of a bone scan is to image the physiology of bones. The drug used for the scan is what your body uses to repair bones. Bones are constantly under repair due to old cells dying, and new cells taking their place so that is why the whole skeleton shows up. So, when there is an increase in the repair of bone, it wills how up brighter on the scan (if black background, it will be more white, and if white background, it will be more black). Hope that answers your question a tad better.
What is a bone density test used for?
Post-menopause unless there's a reason to do it sooner.
What test is used to diagnosis kidney ailment?
MRI Scan and CAT Scan.
What is the difference between a bone scan and a bone density scan?
Bone scans are performed by injecting a radioactive material, that is taken up more rapidly by bone with a relatively high metabolic rate than by bone with a relatively low metabolic rate. In other words, in regions of bone where the bone tissue is undergoing rapid change, the radioactive material will concentrate to a greater degree. Examples of areas where this rapid change occurs are fractures, tumors, areas of inflammation (arthritis), etc. The radioactivity is then read by a special detector which produces an image of the skeleton, enhanced by areas of increased metabolic activity. Bone density scans, on the other hand, are performed with specialized x-ray equipment. It has been known for a long time that a bone's strength is related to how much calcium and other minerals are contained in the bone tissue. It has been further known that bone mineral tends to absorb x-rays. This is why x-rays show bones so well. The bone density (or DEXA) scan measures how much the x-rays are absorbed by the bones and then calculates the relative density of that bone. By comparing the number generated with the normal values, it can be determined whether a patient's bones are abnormal. This test is used primarily to diagnose osteoporosis.

What test checks for osteoporosis?
There are a few different tests which are used to check for osteoporosis. The most common is the DEXA scan. Other methods are blood tests and bone densitometry.
What kind of bone is used for small movements?
small bone :)
What does the acronym FDG stand for?
FDG stands for Fluoro-Deoxy-Glucose, a chemical product used in a medical scan to distinguish various types of lesions from certain types of cancers, which also involved an injection of a tracer radioactive element, which will appear on the scan.
What is physiologic distribution of radiotracer in a petscan?
Physiologic distribution of radiotracer in a pet scan is the normal functional distribution of the radiotracer. The radiotracer is radioactive tracer or radioactive chemical that is used during a pet scan to produce 3-dimensional, color images of the part of the body that is being scanned.

What are some common uses of technetium?
Some common uses of technetium include medical imaging, specifically in the form of radioactive isotopes for bone scans and heart imaging exams. Technetium is also used in industrial applications, such as measuring the thickness of materials and detecting leaks in pipelines. Additionally, it is used in scientific research and as a tracer in environmental studies.
Can tracer bullets be used for hunting?
no
Why can a radioisotope be used as a tracer in the human body?
A radioisotope can be used as a tracer in the human body because tracers are used in the imaging the body's organs and tissues.
What is current tracer?
A current tracer is apen like device used to test the dead circuits. It is used to troubleshhot the logical circuits
What is a bone density test used for?
Post-menopause unless there's a reason to do it sooner.
What is medical procedure code 77080?
It is for a DEXA scan, which is used to measure a woman's bone density..if she has the beginnings of, or a more advanced case of osteoporosis.
